I find that `_etext` needs adjustment and just pushed a commit to fix it.

Hmm. I think splitting this part into a separate PR might be difficult due to the inflexible GitHub PR mechanism.

The test difference is in `lld/test/ELF/x86-64-section-layout.s` below:
```patch
-# CHECK-NEXT: 0000000000205b0a 0 NOTYPE GLOBAL DEFAULT [[#]] (.ldata2) _edata
+# CHECK-NEXT: 0000000000203307 0 NOTYPE GLOBAL DEFAULT [[#]] (.data) _edata
```
